42gears surelock UPGRADE

Affected: >= 2.3.12 and < 2.41.0

Fixed in: 2.41.0

Safe to downgrade to: a release before 2.3.12

1. Check installed version

apt-cache policy surelock || rpm -q surelock || surelock --version

sudo apt update && sudo apt install --only-upgrade surelock

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.3.12 (Debian / Ubuntu)

apt-cache madison surelock sudo apt install surelock=<VERSION_BEFORE_2.3.12> sudo apt-mark hold surelock

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list surelock sudo dnf downgrade surelock-<VERSION_BEFORE_2.3.12> sudo dnf versionlock add surelock

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
